2 Claims.

This invention relates to a self-adjusting collar stay.

An object of this invention is the construction of an eliicient stay device which can be made to fit different size collars. V

Another object of the invention is the construction of a device which is provided with two large loops that can be increased or decreased in size or diameter, with a ring or link for each large loop that holds the loop in place and will not let the loop open sidewise.

With the foregoing and other objects in view, this invention comprises certain novel constructions, combinations, and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a view in elevation, partly shown in section, of a device constructed in accordance with this invention, shown applied to a comparatively wide collar having long points.

Figure 2 is an enlarged view of the device in elevation, while Figure 3 is a top plan view of the same.

Figure 4 is an enlarged sectional view through one of the large loops, showing the ring or link thereon.

Figure 5 is a view in elevation, partly shown in section, of the device applied to a comparatively narrow collar having short points.

As here shown, the invention includes a main portion formed of a single length of bendable wire. Centrally of its length the wire is formed to provide a central bowed portion I, this portion being bowed downwardly in elevation and forwardly in plan as in Figs. 2 and 3. At each end of the central bowed portion the wire is bent to extend diagonally upward and then outwardly as at 2. From each outer end of the portions 2 the wire extends downwardly and forwardly in arms 4 which are slightly bowed towards each other. Each arm 4 has a single relatively large convolution 3 formed close to the portion 2. The convolutions 3 in plan (Fig. 3) form lateral extensions of the bowed portion l. Adjacent their lower extremities each arm 4 has a relatively small convolution 6 below which the arm terminates in a point 1. In the formation of the convolutions the wire from the end of the part 2 closely overlies the wire extending downwardly from said convolution. The invention also in-' cludes keeper rings 5 surrounding the proximal portions of the convolutions so that the convolu- 2 tions may be changed in diameter while held to proper shape. 2

The points 1' are intended to engage in the lining of a collar at its points and the small convolutions 6 prevent excessive penetration of the points 1.

The material from which this device is constructed may be of any suitable spring wire, or the like, which has suflicient springy action to accomplish the desired results.

Normally the device can be applied to the wide collar having the comparatively long points, Fig. 1, but when the device is to be applied to the narrow collar, as shown in Fig. 5, the large loops are expanded, by pressure being applied to the outer portions of the U-shaped portions 2. However, the controlling rings or links 5, on the large loops, will prevent any displacement or distortion of the construction of said large loops, as well as preventing any sidewise movement. Therefore, these large loops 3 at the sides of the U-shaped portions 2, together with the rings or links 5, are essential elements of this efficient and improved device.

Therefore, from the foregoing description it will be apparent that this device is self-adjusting for adaptation to all size collars.

While I have described the preferred embodiment of my invention and illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates during the extensive manufacture of the same, and I, therefore, reserve the right to make such changes or alterations as shall fairly fall within the scope of the appended claims.

What I claim is:

1. A collar stay including a length of bendable wire formed to provide a central forwardly and downwardly bowed portion, said wire having portions extending divergently upwards from the ends of the central bowed portion, said wire having portions extending outwardly from said diverging portions and having arms extending downwardly and forwardly from the last named portions, each of said arms having a relatively large complete convolution formed in its upper portion, said convolutions forming in plan lateral extensions of the bowed portion, said arms terminating at their lower extremities in points, and keeper rings each engaging the wire at adjacent portions of the part forming a convolution.

2. A collar stay including a length of bendable wire formed to provide a central forwardly and downwardly bowed portion, said wire having por= portions of the part forming a convolution, said 4 arms each having a relatively small stop coilvolution adjacent its point.
